To all whom, it may concern.-

Be it known that I, EDUARD RUBIN, a citizen of Switzerland, residing atThun, Switzerland, have invented new and useful Improvements inCartridges, (which have been patented in Switzerland December 21, 1888,No. 189; in Germany January 13, 1889, No. 48,049; in Austria-HungaryJune 4, 1889, No. 15,018, and No. 21,775; in France June17,1889, No.198,998; in England June 20, 1889, No. 10,113, and in Italy June30,1889, No. XXIII, 25,658, L, 380,) of which the following is aspecification.

This invention relates to the manufacture of metal-case cartridges.

The invention will be described with reference to the accompanyingdrawings, forming part of this specification, wherein- Figures 1 and 2show half-sectional elevations of two slightly-different modificationsof the improved cartridge. Fig. 3 shows the bullet-holding packing-ring.Fig. 4: shows a longitudinal section of the compressed charge. The casea is of brass, tombac, or bronze. Its flange b is of the same diameteras the case and is formed by turning a groove 0 in the base of-the casea for the extractor to engage in.

The case is of straight but slightly-tapered form-that is to say, it hasnot the usual bottle-shaped shoulder-and the bullet d is fixed inposition in the end of the case by means of a metalpacking-ringe, (shownseparately in Fig. 3,) which fits tightly around the base of the bulletand within the case of the cartridge. This ring may either be an entirering or split, and it is held in place by burring over the end of thecase, as shown in Fig. 1. The bore of the arm will of course bechambered to correspond to the difference in diameter of thecartridge-case and of the pro- No. 48,049 in Austria-Hungary June 4,

and in Italy June 30, 1889, XXIII,

jectile, and so form an abutment for the front end of thecartridge-case, by which the blow of the striker is resisted in firingand by which the packing-ringis retained in the cartridgecase when theprojectile is discharged.

The employment of the metal packing-ring permits of reloading thecartridge-case with the compressed charge. (Shown in Fig. 4.)

Instead of using the packing-ring e, as above described, and illustratedin Fig. 1, for the purpose of holding the bullet in the case the lattermay be folded or doubled inward on itself, as shown atfin Fig. 2; but inthis example the cartridge-case is not adapted for being reloaded withthe compressed charge, but it may be reloaded with granular powder.

It is evident that the two inner folds of the case in Fig. 2 serve asthe ring E in Fig. l and are in like manner retained in the body of thecase by the inward-extending flange formed on the end of said body.

Having now particularly described and ascertained the nature of the saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is:

In a cartridge of the character specified, the combination, with thecase and the projectile of less diameter than the case, inserted in theend thereof, of a metallic packing-ring surrounding the base of theprojectile within the case, the end of the case being bent inward toform a retainingflange over the packing'ring, substantially as shown anddescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

EDUARD RUBIN.
